Thanks to Hendrik Schwartke for writing the original patch, and to Eric
and Dan for the reviews and suggestions! I squashed the Auditing code
into my earlier modification of Hendrik's bridge-change patch, and
pushed (I also added references to the two open BZes that are related to
this functionality, one upstream and one for RHEL).
